Specifically, the second end 42 is pivotally connected between one ends of the second side walls 31 via the pivot 421, and the connecting wall 32 is connected between the other ends of the second side walls 31. Further, the link 4 has a width corresponding to the interval between the two second side walls 31.

The fixed shaft 5 is fixedly bridged between the two first side walls 11 of the base 1. Therefore, the fixed shaft 5 is fixed to the base 1 to form a stationary member. Specifically, the two first side walls 11 respectively define a fixing hole 111. The two ends of the fixing shaft 5 are respectively inserted into the two fixing holes 111 to form a bridging shape between the two second side walls 11 and the fixing shaft is fixed. 5 passes through the two guide grooves 311 of the slip module 3.

As shown in FIG. 2 , FIG. 4 , FIG. 5 and FIG. 6 , when the user presses the pressing handle 2 by hand, the pressing handle 2 drives the sliding module 3 in the accommodating space 12 via the connecting rod 4 . The sliding action is performed by sliding; and, during the sliding process, the two guide grooves 311 of the sliding module 3 are guided and restricted by the fixed shaft 5 (the sliding amplitude of the sliding module 3 is restricted).

In the first embodiment of the present invention, the driven member 6 is connected to the connecting wall 32 to be crimped, and further includes a clamping member 7 disposed at the other end of the two first side walls 11 for following the sliding. The driven member 6 that moves the shifting module 3 can be press-bonded with respect to the holding member 7. Specifically, the driven member 6 has a crimping member 61 that protrudes from the connecting wall 32, and the crimping member 61 is used for crimping engagement with respect to the clamping member 7.

In addition, a first decorative cover C1 is further positioned on each wall of the sliding module 3, and a decorative shell S is positioned outside the walls of the base 1 to add aesthetics.

As shown in FIG. 7 to FIG. 9, the second embodiment of the present invention is substantially the same as the first embodiment, except that the slip module 3a, the driven member 6a, and the second cover C2 are different. Different, and a set of body 51 and a positioning seat 8 are also added.

Therefore, when the user presses the pressing handle 2 by hand, the pressing handle 2 will slide the sliding module 3a in the accommodating space 12 via the connecting rod 4 to perform a pressure-bonding operation; and, during the sliding process The two guide grooves 311 of the slip module 3a will be guided and restricted by the fixed shaft 5 (the slip amplitude of the slip module 3a is limited).

In the second embodiment of the present invention, the driven member 6a is connected to the other end of the second side wall to be cut by the second side wall, and further includes a positioning seat disposed at the other end of the two first side walls 11. 8. The movable member 6a that moves the following slip module 3a can be cut relative to the positioning seat 8. Specifically, the driven member 6 has a cutting member 62 that protrudes laterally from the second side wall 31a, and the cutting member 62 is used for cutting with respect to the positioning seat 8.

In addition, a second cover C2 is positioned on the two first side walls 11 of the base 1 to add aesthetic appeal.

As shown in FIG. 10 and in conjunction with FIG. 1 to FIG. 9, the present invention further provides a sliding guiding method for a pressing hand tool, which mainly includes the following steps: a base providing step S101, a guiding slot opening step S103, and a sliding The shifting module accommodating step S105 and a fixed shaft fixed bridging step S107.

The base is provided with a step S101: a base 1 is provided, and the base 1 is provided with two first side walls 11 spaced apart from each other to define an accommodation space 12. Of course, one end of the base 1 is pivotally connected with a pressing handle 2, and two ends of a connecting rod 4 are respectively pivotally connected to the pressing handle 2 and the sliding module 3, 3a.

The guiding slot opening step S103: at least one guiding slot 311 is opened in a sliding module 3, 3a. The present invention does not limit the structure of the sliding module 3, 3a, as long as the guiding groove 311 can be opened and can be slid in the accommodating space 12, in the embodiment, as shown in FIG. 1 or FIG. 7 The illustrated structure is taken as an example. As shown in FIG. 1 , the sliding module 3 includes two second side walls 31 spaced apart from each other and a connecting wall 32 connected between the two second side walls 31 . The second side wall 31 is respectively provided with a guiding groove 311. As shown in FIG. 7, the sliding module 3a includes two second side walls 31a spaced apart from each other, and the second side wall 31a is respectively provided with a guide. Slot 311.

The slip module accommodating step S105: the slip module 3, 3a is slidably accommodated in the accommodating space 12.

The fixed shaft fixing bridging step S107: the fixed shaft 5 is fixedly bridged between the two first side walls 11 and the fixed shaft 5 is passed through the two guiding slots 311 of the sliding module 3 (refer to FIG. 1 to As shown in FIG. 6 , at this time, the sliding module 3 can be guided by the fixed guide shaft 5 by the two guiding grooves 311; or the fixed shaft 5 can pass through the two guiding grooves 311 of the sliding module 3a and be supported by Between the two second side walls 31a (refer to FIG. 7 to FIG. 9), at this time, the sliding module 3a can be guided by the fixed shaft 5 by the two guiding grooves 311, preferably, the fixed shaft A set of bodies 51 is also sleeved at the middle of the 5 so that the fixed shaft 5 can be supported between the second side walls 31a by the sleeve 51.

Therefore, when the user presses the pressing handle 2 by hand, and the pressing handle 2 drives the sliding module 3, 3a to slide in the accommodating space 12 via the connecting rod 4, the sliding module 3, 3a will use the same. The two guide grooves 311 are guided by the fixed shaft 5 to slide in the accommodating space 12, and the slip modules 3, 3a are slid together with the two guide grooves 311 with respect to the fixed fixed shaft 5.

In summary, the present invention has the following effects as compared with the prior art system: the guide groove 311 is opened in the sliding module 3, and the fixed shaft 5 is fixedly bridged to the two first side walls 11 of the base 1. The guiding groove 311 is passed through the guiding groove 311 so that the guiding groove 311 is not covered by the first side wall 11 , so that the guiding groove 311 can be easily damaged and not easily fouled due to no exposure.

In addition, the creative system has other functions: the link 4 is pivotally connected to the second side wall 31, 31a of the sliding module 3, 3a, and the second side wall 31, 31a is opened. The portions of the guide groove 311 are offset from each other, that is, the portion guided by the link 4 and the portion guided by the fixed shaft 5 are offset from each other (or different from each other) to allow the amount of power of the link 4 to be guided by the fixed shaft 5. The force is not concentrated in one place of the slip modules 3, 3a, but is dispersed in two places, so that the structure is not easily damaged. Since the connecting rod 4 has a width corresponding to the spacing between the two second side walls 31, 31a, when the connecting rod 4 is pushed and pulled corresponding to the pivot 421 by this width, the dragging force of the push-pull will be The force is a line contact, thereby improving the conventional lack of point contact to push and pull and being easily damaged (because of excessive stress concentration).

The above is only a preferred and feasible embodiment of the present invention, and thus does not limit the scope of the patent of the creation, and the equivalent structural changes that are made by using the present specification and the contents of the schema are all included in the creation. Within the scope of the rights, it is given to Chen Ming.
