Background

Mechanical keyboards are favored by many computer users, programmers, and game players, where each key has a separate switch, also called a "key", for controlling the closing, and the switches are classified according to the switch classification as "tea", green ", white, black, red, Romer-G", and optic. Just because each key is controlled by a separate switch, the sectional feeling of the keys is strong, thereby generating a special hand feeling suitable for game entertainment.

Structurally, each shaft switch of the mechanical keyboard generally comprises a shell, a press handle connected to the shell in a sliding manner, and a conduction assembly (such as elastic contact conduction, optical contact induction conduction, magnetic induction conduction, electrostatic capacitance induction conduction, silica gel contact conduction and the like) arranged in the shell, wherein the conduction assembly is electrically connected to a circuit board, and the press handle can be switched on and off when moving under stress, so that the input or disconnection of the keyboard is realized. According to user's user demand, still add the sound production structure of feeling on some press handles to make and press the handle and produce the impact sound and shake the hand feeling at the removal in-process.

The existing shaft switch has the following defects: for an axle switch needing to generate impact sound and not needing to generate the impact sound, the axle switch needs to be designed and produced respectively as two products, and two different functions and handfeels can be realized only by simply changing the structure of one product, so that the production cost of manufacturers is higher; secondly, the press handle of the shaft switch usually has a large area, most of users are difficult to press the center of the press handle in the using process, and when the users press the edge position of the press handle, the press handle can be inclined, so that the press handle can interfere with the structure outside the press handle in the moving process, the clicking hand feeling is generated, and the user using experience is reduced.

Referring to fig. 1 to 16, the elastic mechanical shaft 1 of the present invention includes a mounting base 100, a pressing handle 200, a sliding member 300, a conducting member 400, a metal terminal 500, a first elastic member 600, and a second elastic member 700. The top surface of the mounting base 100 is provided with a through hole 111, the bottom surface of the mounting base 100 is provided with a base hole 122, the metal terminal 500 is mounted at the bottom of the mounting base 100, and one end of the metal terminal 500 protrudes out of the mounting base 100. The pressing handle 200 is movably installed on the installation base 100, and the upper end thereof protrudes out of the installation base 100 through the through hole 111, the sliding member 300 is movably installed in the installation base 100 and located below the pressing handle 200, and the conduction member 400 is installed on the sliding member 300. When the handle 200 moves, the slider 300 can be driven to move, so that the slider 300 acts on the bottom surface of the mounting seat 100 or/and slides into the base hole 122, and thus a paragraph hand feeling or a linear hand feeling is generated, and the slider 300 optionally impacts the bottom surface of the mounting seat 100 or the bottom surface of the base hole 122, so that impact sound is selectively generated, namely, the paragraph hand feeling and the impact sound are simultaneously generated, or the paragraph hand feeling and the sound are not generated, or the linear hand feeling and the impact sound are generated, or the linear hand feeling and the sound are generated, so that different user requirements are met, and the user experience is increased; in addition, manufacturers can produce products with different functions and hand feelings only by simple structural changes, so that the production cost is reduced. In the moving process of the sliding member 300, the conducting member 400 is driven to move so as to be detachably abutted to the metal terminal 500, thereby implementing the connection and disconnection of the signal.

In the present invention, one end of the first elastic member 600 abuts against the press handle 200, and the other end abuts against the slider 300 or the conducting member 400, and the elastic force of the first elastic member 600 can drive the slider 300 to enter the base hole 122 and strike the bottom surface of the mounting base 100, thereby generating a strong and crisp impact sound, enhancing the user experience, and enabling the conducting member 400 to detachably abut against the metal terminal 500, and also driving the press handle 200 to move and reset. Both ends of the second elastic member 700 respectively abut against the bottom of the pressing handle 200 and the bottom of the mounting seat 100, and the elastic force of the second elastic member 700 drives the pressing handle 200 to move and reset.

Referring to fig. 1-4, in the present invention, the mounting base 100 includes a base cover 110 and a base 120 that are coupled to each other in a vertical manner. The top surface of the base cover 110 is provided with the through hole 111, and meanwhile, two

opposite side walls

110a and 110b of the base cover 110 are respectively provided with a connecting sheet 112 protruding downward, two ends of each connecting sheet 112 are provided with first buckles 113 protruding transversely, and the two first buckles 113 on each connecting sheet 112 protrude in opposite directions, as shown in fig. 4. Correspondingly, the interior of the base 120 is hollow to form an installation cavity 121, and the base hole 122 is opened at the approximate middle part of the bottom surface of the base 120; in addition, the outer sides of the two

opposite side walls

120a, 120b of the base 120 are provided with second latches 125, and the side wall 120a is provided with two symmetrical second latches 125, and the two second latches 125 both protrude in a direction perpendicular to the side wall 120a, as shown in fig. 4, the arrangement of the second latches 125 on the side wall 120b is the same as that on the side wall 120a, and the description is not repeated. When the base cover 110 is connected to the base 120, the base cover 110 is disposed above the base 120, and the sidewall 110a corresponds to the sidewall 120a, the sidewall 110b corresponds to the sidewall 120b, the connecting piece 112 below the sidewall 110a moves downward along the sidewall 120a, so that the first buckle 113 on the connecting piece 112 passes over the second buckle 125 and is engaged with the second buckle 125, and correspondingly, the first buckle 113 on the connecting piece 112 below the sidewall 110b is engaged with the second buckle 125 on the sidewall 120b, thereby achieving the engagement connection between the base cover 11 and the base 120.

Referring now to fig. 7-8 and 12-16, in one embodiment of the present invention, the slider 300 is offset from the base hole 122 and the centerline of the handle 200, such that the slider 300 has a first position (shown in fig. 13-14) offset from the base hole 122 and a second position (shown in fig. 15-16) corresponding to the base hole 122, i.e., the slider 300 is in the first position, the centerline of the slider is not concentric with the centerline of the handle 200, but is in an eccentric position with respect to the centerline of the handle 200; when the slider 300 is in the second position, the center line thereof is concentric with the center line of the knob 200. Therefore, when the slider 300 is in the first position, the handle 200 can drive the slider 300 to move downward and make it act on the bottom surface of the mounting seat 100, and the slider 300 can also be driven by the handle 200 to move from the first position to the second position, i.e., the slider 300 is moved to the position right above the base hole 122, and the slider 300 can slide into the base hole 122, and then slide into the base hole 122 after acting on the bottom surface of the mounting seat 100 by the slider 300, thereby generating a strong paragraph feel. When the sliding member 300 slides into the base hole 122, it may impact the bottom surface of the base hole 122 to generate an impact sound, or may not impact the bottom surface of the base hole 122, and at this time, no impact sound will be generated, that is, according to specific functional requirements, the bottom end of the sliding member 300 is selectively made to impact the bottom surface of the base hole 122 or not, so that the elastic mechanical shaft 1 may further generate an impact sound or no impact sound while having a paragraph hand feeling, thereby satisfying the use experience requirements of different users. For manufacturers, the length of the bottom end of the sliding member 300 and/or the bottom surface structure of the base hole 122 need to be slightly changed during production, so that the elastic mechanical shaft 1 has paragraph hand feeling and further generates impact sound or does not generate impact sound, and therefore, different functional requirements can be met by simply changing the same product, and the production cost is reduced.

It is understood that the pressing handle 200 may not drive the slider 300 to move from the first position to the second position, i.e. only drive the slider 300 to move at the first position or the second position, so that the slider 300 only acts on the bottom surface of the mounting seat 100 or the bottom surface of the seat hole 122. Of course, the slider 300 is not limited to the above-mentioned offset arrangement, and may be arranged just opposite to the bottom surface of the mounting seat 100 or just opposite to the seat hole 122. In both of the above two modes, the pressing handle 200 only drives the slider 300 to move at the first position or the second position, so that the slider 300 only acts on the bottom surface of the mounting seat 100 or the bottom surface of the seat hole 122, thereby generating a strong linear feeling; and, the slider 300 is selectively made to strike the bottom surface of the mount 100 or the bottom surface of the mount hole 122, thereby further generating the striking sound or not generating the striking sound, i.e., having a linear hand feeling and the striking sound, or having a linear hand feeling without sound, satisfying different user demands, and increasing the user experience.

As shown in fig. 7-8 and 13-16, in an embodiment of the present invention, an upwardly protruding bottom boss 123 is provided on the bottom surface of the base hole 122, and after the slider 300 slides into the base hole 122, the slider directly hits the bottom boss 123 to generate a hitting sound. In this embodiment, by changing the height of the bottom boss 123, the bottom end of the slider 300 cannot directly impact the bottom boss 123, i.e., the slider does not generate sound, and it is easier for manufacturers to change the product functions and lower the production cost.

As shown in fig. 1 to 11 and 13, in an embodiment of the present invention, the metal terminal 500 includes two metal terminals, which are respectively referred to as a first metal terminal 500a and a second metal terminal 500b for convenience of description, as shown in fig. 4. The first metal terminal 500a and the second metal terminal 500b are mounted on the bottom surface of the mounting base 100 at intervals along the first direction, in this embodiment, the first metal terminal 500a and the second metal terminal 500b are mounted on the bottom surface of the mounting base 100 at intervals along the X-axis direction, as shown in fig. 4 and 13, and the other ends of the first metal terminal 500a and the second metal terminal 500b protrude out of the mounting base 100. When the slider 300 drives the conducting element 400 to move downward, the two ends of the conducting element 400 can be separately abutted to the first metal terminal 500a and the second metal terminal 500b, so as to achieve the connection and disconnection of the signal.

With continued reference to fig. 4 and 9, the first metal terminal 500a has a first electrical connection portion 510, a first protrusion 511 is disposed on a top surface of the first electrical connection portion 510, the second metal terminal 500b has a second electrical connection portion 520, and a top surface of the second electrical connection portion 520 is a planar structure. As shown in fig. 7-9 and 13, one end of the conducting element 400 is provided with a second protrusion 410 protruding downward, and the other end of the conducting element 400 is bent downward to form a bent end 420, after the conducting element 400 is installed, the second protrusion 410 corresponds to the first protrusion 511, and the bent end 420 corresponds to the second electrical connection part 520, so that after the conducting element 400 moves, the second protrusion 410 and the first protrusion 511 can be separately abutted, and the bent end 420 and the second electrical connection part 520 can be separately abutted. It is to be understood that the shapes of the first metal terminal 500a, the second metal terminal 500b and the conductive member 400 are not limited to those of the present embodiment, and may be any other shapes as needed, and the mounting positions of the first metal terminal 500a and the second metal terminal 500b may be interchanged.

When the handle 200 is connected to the slider 300, the first hook 231 at the lower end of the handle 200 is engaged with the second hook 321. The handle 200 can move downward along the two sidewalls 320 of the slider 300, and can drive the slider 300 to move downward in an inclined manner for a certain distance, so that the protruding pillar 330 of the slider 300 abuts against the installation boss 124a, at this time, the first inclined surface 232 on the slider contacts with the second inclined surface 322, the handle 200 continues to move downward to push the slider 300 to slide horizontally, that is, the slider 300 moves from the first position to the second position, so that the protruding pillar 330 of the slider 300 falls into the base hole 122 from the installation boss 124a, as shown in fig. 11-15.

Referring again to fig. 7-16, in an embodiment of the present invention, a positioning post 240 is further protruded from a lower portion of the body 210, and the positioning post 240 is disposed in an inclined manner, that is, the positioning post 240 is offset from a center line of the pressing handle 200 or the pressing post 220. After the pressing handle 200 is mounted on the mounting base 100, the center line of the pressing handle 200 or the pressing post 220 is preferably coincident with or parallel to the center line of the base hole 122, and the positioning post 240 is offset from the center lines of the pressing handle 200 and the base hole 122 and protrudes obliquely toward the mounting boss 124a, as shown in fig. 8 and 13-15.

More specifically, one end of the first elastic element 600 is sleeved on the positioning post 240 and abuts against the body 210 of the pressing handle 200, and the other end abuts against the conducting element 400 or the sliding element 300, in this embodiment, the top of the conducting element 400 has a positioning protrusion 430 protruding upward, the first elastic element 600 is sleeved on the positioning protrusion 430 and abuts against the conducting element 400, so that the conducting element 400 is tightly attached to the inner cavity of the sliding element 300, and the first elastic element 600 is disposed in an inclined manner, as shown in fig. 8-11 and fig. 14-16.

Referring to fig. 3 to 16, in the present invention, the second elastic member 700 is sleeved outside the push rod 230, and two ends of the second elastic member 700 respectively abut against the bottom surfaces of the body 210 and the mounting seat 100, and the elastic force of the second elastic member 700 is overcome in the downward movement process of the pressing handle 200, so that when the pressing handle 200 loses the acting force, the elastic force of the second elastic member 700 restoring deformation drives the pressing handle 200 to move upward and return.

As shown in fig. 13-16, when the pressing handle 200 is pressed, the pressing handle will overcome the elastic force of the first elastic member 600 and the second elastic member 700 to move downward, in this process, the first elastic member 600 pushes the sliding member 300 and the conducting member 400 to move downward in an inclined manner, specifically, the sliding member 300 moves toward the mounting boss 124a in an inclined manner, that is, the sliding member 300 generates downward and horizontal displacement, and when the convex pillar 330 at the lower end of the sliding member 300 abuts against the mounting boss 124a, as shown in fig. 13, the first inclined surface 232 of the pressing handle 200 contacts with the second inclined surface 322 of the sliding member 300.

The pressing handle 200 further moves downward against the elastic force of the second elastic member 700, so that the first elastic member 600 is further compressed, in the process, the first inclined surface 232 acts on the second inclined surface 322 of the slider 300, thereby pushing the slider 300 to move horizontally, when the first elastic member 600 is compressed to the maximum extent, the slider 300 moves horizontally to just get away from the mounting boss 124a, at which time the slider 300 moves above the base hole 122 and drops into the base hole 122 instantaneously, in the process, the bottom end of the slider 300 loses the acting force, so that the elastic force generated by the recovery deformation of the first elastic member 600 drives the slider 300 to hit the bottom boss 123 in the base hole 122, as shown in fig. 15-16, thereby generating a strong and crisp impact sound and generating a strong paragraph feeling (pause feeling), thereby enhancing the user experience. At the same time, the conduction piece 400 descends and is pressed against the first and

second metal terminals

500a and 500b by the first elastic piece 600, so that signal conduction is realized.

In the invention, the first elastic member 600 and the second elastic member 700 are preferably springs, the spring technology is mature, the elasticity is easy to control, and a large elastic force can be generated, so that strong vibration hand feeling and impact sound are ensured, and the press handle 200 is ensured to be rapidly reset. Of course, the first elastic member 600 and the second elastic member 700 are not limited to springs, and other elastic elements may be used to implement the present invention.

Referring to fig. 3 to 16 again, in another preferred embodiment of the present invention, the elastic mechanical shaft 1 further includes a balance mechanism 800, the balance mechanism 800 is installed in the mounting seat 100, and two ends of the balance mechanism 800 are respectively connected to the pressing handle 200 and the mounting seat 100, when the pressing handle 200 moves, the balance mechanism 800 is driven to operate accordingly, the pressing handle 200 is kept moving back and forth along the vertical direction (Z-axis direction) by the balance mechanism 800, thereby preventing the pressing handle 200 from tilting when the pressing handle is unevenly stressed, and further avoiding the interference between the pressing handle 200 and the structure outside the pressing handle 200 (for example, the inner wall of the mounting seat 100) during the moving process, so that the pressing handle 200 moves up and down more smoothly, and thus the user does not feel a stuttering when using the elastic mechanical shaft, and the user experience is enhanced.

Referring to fig. 4, in an embodiment of the present invention, the balance mechanism 800 includes two balance assemblies symmetrically disposed, and for convenience of description, the two balance assemblies are respectively referred to as a first balance assembly 810 and a second balance assembly 820. The first balance components 810 and the second balance components 820 are arranged at intervals along a first direction, that is, arranged at intervals along the X-axis direction, the upper ends of the first balance components 810 and the second balance components 820 are respectively connected to the two

side walls

210a and 210b of the body 210, the lower ends of the first balance components 810 and the second balance components 820 are respectively connected to the bottom of the mounting base 100, and when the press handle 200 moves up and down, the first balance components 810 and the second balance components 820 on the two sides of the press handle are driven to synchronously move so as to keep the press handle 200 to stably move back and forth along the vertical direction (the Z-axis direction).

In the present embodiment, the first balancer 810 and the second balancer 820 have the same structure, and the first balancer 810 will be described as an example. Specifically, the first balance assembly 810 includes a first balance bar 811 and a second balance bar 812, the first balance bar 811 and the second balance bar 812 are disposed in a crossed manner, and the middle portions of the first balance bar 811 and the second balance bar 812 are pivoted, one end of the first balance bar 811 is pivoted to the pressing handle 200 or the mounting base 100, and the other end of the first balance bar 811 is slidably connected to the pressing handle 200 or the mounting base 100. Correspondingly, one end of the second balance bar 812 is pivotally connected to the pressing handle 200 or the mounting base 100, and the other end of the second balance bar 812 is slidably connected to the pressing handle 200 or the mounting base 100. Therefore, when the press handle 200 moves, the first balance bar 811 and the second balance bar 812 are driven to pivot with each other, and one end of the first balance bar 811 or the second balance bar 812 slides along the press handle 200 or the mounting base 100, so that the press handle 200 is kept to move in the vertical direction (Z-axis direction), the moving process of the press handle 200 is smoother, a user does not feel a stuck hand when using the press handle, and the user experience is enhanced.

With continued reference to fig. 3-4 and 6-7, in the present embodiment, the upper end of the first balance bar 811 is pivotally connected to the body 210, and the lower end of the first balance bar 811 is slidably connected to the mounting base 100, although the arrangement of the two ends can be interchanged. Correspondingly, the upper end of the second balance bar 812 is slidably connected to the body 210, and the lower end of the first balance bar 811 is pivotally connected to the mounting base 100, although the arrangement of the two ends may be interchanged. Therefore, when the pressing handle 200 is forced to move downward, the upper ends of the first and second balance bars 811 and 812 are pushed to move downward, thereby pivoting the upper end of the first balance bar 811 and pushing the lower end thereof to horizontally slide along the mounting seat 100, and correspondingly, the pressing handle 200 pushes the upper end of the second balance bar 812 to horizontally slide along the body 210, thereby pivoting the lower end thereof with respect to the mounting seat 100, while relatively pivoting between the first and second balance bars 811 and 812, thereby maintaining the pressing handle 200 to move vertically downward.

With reference to fig. 6 to 7 and fig. 3 to 4, in the present embodiment, a first upper connecting shaft 8111 is protruded from an upper end of the first balance bar 811, a first lower connecting shaft 8112 is protruded from a lower end of the first balance bar 811, and axial directions of the first upper connecting shaft 8111 and the first lower connecting shaft 8112 are the same. Correspondingly, a second upper connecting shaft 8121 is convexly arranged at the upper end of the second balance bar 812, a second lower connecting shaft 8122 is convexly arranged at the lower end of the second balance bar, and the axial directions of the second upper connecting shaft 8121 and the second lower connecting shaft 8122 are the same. When the first balance bar 811 and the second balance bar 812 are pivoted, the first upper connecting shaft 8111 and the first lower connecting shaft 8112, the second upper connecting shaft 8121 and the second lower connecting shaft 8122 protrude in opposite directions, as shown in fig. 4.

With reference to fig. 4, the upper end of the first balance component 810 is connected to the sidewall 210a of the body 210, two ends of the sidewall 210a are respectively provided with a first pivot hole 211 and a first sliding slot 212, and the first sliding slot 212 extends along the Y axis. Two symmetrical pivoting seats 126 are disposed at one end of the bottom of the base 120, each pivoting seat 126 is provided with a second pivoting hole, and two symmetrical second sliding grooves 127 are disposed at the other end of the bottom of the mounting seat 100. In the present embodiment, the pivot seat 126 and the second sliding slot 127 are disposed at intervals along the Y-axis direction, as shown in fig. 4.

When the first balance assembly 810 is installed, the first upper connecting shaft 8111 of the first balance bar 811 is pivoted in the first pivoting hole 211 on the sidewall 210a, and the first lower connecting shaft 8112 is slidably connected in the second sliding groove 127; the second upper connecting shaft 8121 of the second balance bar 812 is slidably connected to the first sliding slot 212 of the sidewall 211, and the second lower connecting shaft 8122 is pivotally connected to the second pivot hole.

In the present invention, the second balance assembly 820 also includes a first balance bar 821 and a second balance bar 822 pivotally connected to each other, wherein the first balance bar 821 has the same structure as the first balance bar 811, and the second balance bar 822 has the same structure as the second balance bar 812. After the installation, the middle portions of the first balance bar 821 and the second balance bar 822 are pivoted, and the first upper connecting shaft 8211 of the first balance bar 821 is pivoted in the first pivoting hole of the other side wall 210b of the body 210, the first lower connecting shaft 8212 is slidably connected in the second sliding groove 127, the second upper connecting shaft 8221 of the second balance bar 822 is slidably connected in the first sliding groove of the side wall 210b, and the second lower connecting shaft 8222 is pivoted in the second pivoting hole. The principle of the second balancing assembly 820 is the same as that of the first balancing assembly 810, and a description thereof will not be repeated.

More preferably, the upper ends or the lower ends of the first balance bars 811 and 821 may be integrally connected or formed, and correspondingly, the upper ends or the lower ends of the second balance bars 812 and 822 may be integrally connected or formed, so as to facilitate production and installation. In one embodiment, the upper ends of the first and second balance bars 811 and 821 are connected, and the lower ends of the second and second balance bars 812 and 822 are connected, as shown in fig. 4.

The working principle and process of the elastic mechanical shaft 1 of the present invention will be described with reference to fig. 1-16 again.

When the pressing handle 200 is in the initial state, the pressing post 220 protrudes from the top of the mounting base 100, and the elastic force of the second elastic member 700 causes the body 210 to abut against the base cover 110, as shown in fig. 1, 3, and 14, at this time, the upper end of the first elastic member 600 is sleeved on the positioning post 240 and abuts against the body 210 of the pressing handle 200, the other end of the first elastic member 600 abuts against the conducting member 400, the elastic force of the first elastic member 600 causes the conducting member 400 to cling to the inner cavity of the sliding member 300, and causes the second hook 321 of the sliding member 300 to engage with the first hook 231 of the pressing handle 200, as shown in fig. 11-12. Meanwhile, the center line of the slider 300 is offset from the center line of the handle 200, that is, the center lines of the slider 300 and the handle 200 are not concentric, and the slider 300 is located at an eccentric position with respect to the center line of the handle 200.

When the top of the pressing post 220 of the pressing handle 200 is pressed, the pressing handle 200 moves downward along the Z-axis against the elastic force of the first elastic member 600 and the second elastic member 700, and during the downward movement of the pressing handle 200, the inclined first elastic member 600 pushes the conducting member 400 and the sliding member 300 to move obliquely downward until the bottom of the protruding column 330 of the sliding member 300 abuts against the mounting boss 124a, as shown in fig. 14, the sliding member 300 horizontally displaces, so that the second inclined surface 322 thereof contacts with the first inclined surface 232 of the pressing handle 200.

When the pressing handle 200 continues to be pressed to overcome the elastic force of the second elastic member 700 and move downwards, the first elastic member 600 is compressed, in this process, the first inclined surface 232 of the pressing handle 200 abuts against the second inclined surface 322 of the sliding member 300, the sliding member 300 is pushed to move horizontally through the interaction of the first inclined surface 232 and the second inclined surface 322, when the first elastic member 600 is compressed to the maximum extent, the sliding member 300 moves horizontally to just separate from the mounting boss 124a, at this time, the bottom end of the sliding member 300 loses acting force, so that the elastic force generated by the deformation recovery of the first elastic member 600 drives the sliding member 300 to move downwards to enable the convex column 330 to fall into the base hole 122, and simultaneously the elastic force of the first elastic member 600 enables the convex column 330 to impact the bottom boss 123 in the base hole 122, as shown in fig. 15, thereby generating a crisp impact sound, and simultaneously, the convex column 330 of the sliding member 300 abuts against the mounting boss 124a and then falls into the base hole 122, therefore, strong paragraph hand feeling is generated, namely, the paragraph hand feeling and the impact sound are provided at the same time, and the use experience is enhanced. Understandably, if the protruding pillar 330 of the sliding member 300 abuts against the installation boss 124a and then falls into the base hole 122, it will not hit the bottom boss 123 in the base hole 122, so that there is a touch of paragraph without sound.

After the slider 300 falls into the base hole 122, the conductive piece 400 thereon is pressed by the first elastic piece 600, and both ends of the conductive piece abut against the first metal terminal 500a and the second metal terminal 500b, as shown in fig. 15, so as to realize signal conduction. The pressing handle 200 continues to be pressed downward, and the first elastic member 600 is compressed again, as shown in fig. 16.

When the pressing handle 200 is released, the elastic force generated by the deformation of the first elastic member 600 and the second elastic member 700 pushes the pressing handle 200 to move upward for resetting, and after the pressing handle 200 moves upward for a certain distance, the first hook 231 on the pushing rod 230 is engaged with the second hook 321 of the sliding member 300, as shown in fig. 7, 9 and 12, so as to pull the sliding member 300 to synchronously continue moving upward for resetting, and at the same time, the elastic force of the first elastic member 600 also drives the sliding member 300 to move downward for resetting to the initial position, i.e., to return to the position where the center line of the sliding member 300 and the center line of the pressing handle 200 are arranged in a staggered manner. When the pressing handle 200 moves upwards and returns to the initial position, the flexible gasket arranged on the pressing handle can impact the top of the mounting seat 100, so that the sound of rebounding impact on the wall is reduced, the silencing effect is achieved, and a silencing shaft is formed. In the above process, the sliding member 300 drives the conducting member 400 thereon to move upwards synchronously, so that the conducting member 400 is separated from the first metal terminal 500a and the second metal terminal 500b, thereby realizing signal disconnection.

Furthermore, during the downward or upward movement of the press handle 200, the first balance bar 811 and the second balance bar 812 of the first balance assembly 810 are driven to pivot with each other, and the first balance bar 821 and the second balance bar 822 of the second balance assembly 820 are driven to pivot with each other, so that the press handle 200 can keep moving in the vertical direction (Z-axis direction) during the downward or upward movement by the force applied to the balance press handle 200 of the second balance assembly 820 and the second balance assembly 820 arranged opposite to each other on the two sides of the body 210, and will not interfere with the inner wall of the mounting base 100 or other components, thereby making the movement of the press handle 200 smoother, and the user will not feel a stuck hand during use, thereby enhancing the user experience.

As described above, in the elastic mechanical shaft 1 of the present invention, the base hole 122 is formed on the bottom surface of the mounting base 100, the pressing lever 200 is movably mounted on the mounting base 100, the slider 300 is movably mounted in the mounting base 100 below the pressing lever 200, and the conduction member 400 is mounted on the slider 300. Therefore, when the pressing handle 200 moves, the sliding member 300 and the conducting member 400 can be driven to move, and first, the conducting member 400 is detachably abutted to the metal terminal 500 to realize the on-off of the signal; secondly, the slider 300 is made to act on the bottom surface of the mounting seat 100 or/and the bottom surface of the base hole 122, so that a paragraph hand feeling or a linear hand feeling is generated, and the slider 300 optionally collides with the bottom surface of the mounting seat 100 or the bottom surface of the base hole 122 as required, so that an impact sound is optionally generated or not generated, that is, the paragraph hand feeling and the impact sound are simultaneously generated, or the paragraph hand feeling and no sound are generated, or the linear hand feeling and the impact sound are generated, or the linear hand feeling and no sound are generated, so that different user requirements are met, and the user experience is increased; moreover, the manufacturer only needs to carry out minor changes to the length of the bottom end of the sliding part 300 or/and the bottom surface structure of the base hole 122 during production, and the elastic mechanical shaft 1 can further generate impact sound or not generate impact sound while having paragraph hand feeling, or further generate impact sound or not generate impact sound while having linear hand feeling strong, so that different functional requirements and effects can be realized by simply changing the same product, and the production cost is reduced.
