Description

M286100 Creation Instructions (1) [New Technology Fields]·· This creation system makes the tool head and its rotation levers better. The main technology and purpose are as follows: Only one of them, the rod body is set to have two ends running through the hollow shape, and a plurality of tool heads are inserted therein to form a collecting tool head, and the function of preventing the tool head from being lost is provided at the end of the rod body. The telescopic hole, the inclined surface positioning block and the elastic ring are connected, and the tool head is provided with a corresponding oblique groove, and the positioning block is inserted into the oblique groove to form a jamming tool head, so as to prevent detachment and be used for normal force application. Prior art]:

According to the conventionally-removable screwdriver tool head structure, generally shown in Fig. 1 (A) and (β), the system is: a solid rod body, and the rear end is provided with a plug portion 11 for inserting into the grip. Or the other sleeve tool, the front end is provided with the insertion hole 12 for inserting the screwdriver tool head 1, and in order to prevent the tool head from being easily detached, an elastic ring is embedded in the outer circumference of the rod body 1 1 6, the ring groove 13 is provided with a connecting telescopic hole 1 4 to assemble the steel ball 15 5, by the elastic ring 16 elastic force, the steel ball 15 , to resist the tool head 1 to prevent detachment; above, there are actually the following disadvantages:

The rod body 10 is set to be solid to block the tool head 1, and therefore, the tool head 1 cannot be stored in the rod body 1 and the size of the tool head 1 is limited. It is diversified and available in a variety of sizes. Therefore, when it comes to a number of different tool heads, it must be stored in a box, which is inconvenient and easy to lose. (2) The detachment of the tool head 1 is easy to disengage when the steel ball 15 is in the plane of the tool head 1 when the elastic ring 16 is weakened (induced by elastic fatigue).

Page 6 M286100 Creation Instructions (2) 虞. [New content]: Referring to Figures 2 and 3, the system includes: a rod body 2 with a matching hole 21: a plurality of tool heads 2, a ring groove 22 is provided on the outer periphery of the front end of the rod body 2, and a ring groove 22 is formed in the ring groove 22 Further, the hole 23 is stretched, and the positioning block 24 and the elastic ring 25 are assembled to abut the tool head 2 to prevent erroneous detachment; and the insertion hole 21 of the body 20 is configured to penetrate the rod body 2 The tool body 2 is disposed in a hollow shape, and the plurality of tool heads 2 are inserted into the rod body; the positioning block 24 is provided with a sloped surface 24; The bevel groove 3 is inserted into the rod insertion hole & hole 2 in the tool head 2, and the bottom end of the clamping block 24 can be inserted into the bevel groove 3 of the tool head 2 to form a tool for positioning the tool head 2. The head 2 is not advanced and disengaged when it is not subjected to the thrust, and the force is not retracted; the rear end of the rod body 20 is provided with a ring groove 26 at the outer circumference, and the ring groove 26 has a telescopic hole 27 therethrough, and the steel ball 28 and the elastic ring 29 are assembled. The steel ball 28 can be pressed against the tool head 2 to prevent the tool head 2 from being accidentally pulled out by the rear end of the rod body 20; the rear end of the rod body 20 is integrally provided with the rod body 2〇. The sleeve 4, to form an enlarged diameter, so that the rod can be obtained directly without having to plug 2〇 the grip. _ [Implementation]: The use of this creation: As shown in Figure 3, each tool head 2 is inserted from the rear end hole of the rod 20 respectively, so that a tool head 2 is exposed to expose the front end of the rod body 2, and other tool heads 2 They are all hidden in the body 20. The exposed tool head 2 can be used for rotating screws and screws.

M286100 IV. Creation Instructions (3) However, this creation can produce the following functions and advantages: (1) It is convenient for collecting multiple tool heads 2, so that multiple tool heads 2 are not easy to lose jobs. (2) LI changer head · 'Extract the exposed tool head from the rod movement = insert the rod body 2 to the rear end and insert the rod body 2. In the middle, the tool heads of the gossip are pushed forward and the operation is performed until the required tool head is exposed. The use is extremely convenient. 1 is easy. 2, the 4 work 2 is provided with a bevel groove 3, and the rod body 20 is provided with a bevel 240 positioning block. 24, can get the following effects: & ι· s head pressing screw, screw rotation, because the positioning block 24 bevel 240 - inserted into the bevel groove 3, forming a barbed blocking effect, thus blocking the tool head 2, Therefore, the tool head does not retreat due to the top pressure, and the effect of being able to press and rotate strongly can be achieved. 2. When the tool head is to be replaced (disengaged), since the positioning block 24 has a slope 240 and the angled groove 3 also has a slope angle, the elastic ring 25 can be elastically enlarged to expand the diameter, so that the positioning block 24 can be retracted outward. Let the tool head 2 be smoothly pulled away from the shaft 2 〇. ...

(5) (6) The rear end of the rod body 20 is provided with a telescopic hole 27, a steel ball 28, and an elastic ring 29, and the steel ball 28 has a pressure against the tool head 2, thereby preventing the tool head from being erroneously detached from the rear end of the rod body 20. . The body 20 has a grip sleeve $ on the outer circumference of the rear end, which has an enlarged rod diameter, so that it can be used for direct hand rotation. The tool body 20 can also be inserted into a tool head at the rear end of the rod body 20, and the tool head is exposed.

M286100 creation instructions (4), and can be plugged in with other tools (for example: the connector of the electric screwdriver) together with the use. Moreover, according to the above technical means, the creation can also be implemented in the form of figures 4 and 5:

In the fourth embodiment, the rear end of the rod body 20 is provided with an integrally formed extension portion 201 (in an L shape) at an angle of ninety degrees. The extension portion 201 has a through hole 2〇2 communicating with the rod body 20, and is in communication. The blocking block 3〇, the spring 31, and the closing block 32' are formed in the hole 2〇2 to form an effect of blocking the tool head 2 in the end of the rod body 2 from being detached by the tool head 2, and the extension piece 2〇1 end through hole The tool head 2 is inserted into the tool head 2, and the end of the tool head 2 can be used for plugging other tools. The outer circumference of the extension end of the extension section is provided with a ring groove for inserting an elastic ring 2, and the slot is provided with a telescopic joint. The hole 27 is for assembling the steel ball 28, and the steel ball 28 is obtained against the effect of the tool head 2 preventing the escape. 2. In Fig. 5, the tie body 20 is provided with a plurality of side holes 2〇3, and each side hole 2〇3 corresponds to each of the tool heads 2' to obtain the specifications of the respective tool heads in the rod body 2〇. In summary, the structure of this creation does have excellent practicality and efficiency, and it is in line with the new patent principle, so please grant a patent.
