[0036] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the present application will be described in detail below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0037] Referring to Figures 1 to 7 , the present embodiment provides a wrench and sleeve connecting piece device which can be used for assembling both internal hexagonal bolts and external hexagonal bolts. The wrench and sleeve connecting piece device comprises a sleeve 100, a connecting piece 200, a wrench 300, a spring 400, a quick pull gun head 500, a positioning pin 600, an annular elastic member 700 and a magnet 800.

[0038] The sleeve 100 has an axial hole 110, one end of which is configured as a first wrenching part 111 adapted to an external hexagonal bolt, and the other end is configured as a square hole as a mounting part 112; on the outer wall of the sleeve 100, a groove 120 is arranged around one end of the mounting part 112, and three through holes 130 are arranged in the groove 120 and communicate with the inside of the mounting part 112.

[0039] The connecting piece 200 is configured as a square structure and is arranged in the mounting part 112 of the hole 110, and since the connecting piece 200 and the mounting part 112 are both square, they cannot rotate relative to each other; the connecting piece 200 has an axial shuttle hole 210, and the outer wall of the connecting piece 200 is provided with three limit holes 220 uniformly distributed in the circumferential direction; when the connecting piece 200 is placed in the mounting part 112, the positioning pin 600 can be used to pass through the through hole 130 and the limit hole 220 in sequence from the outer wall of the sleeve 100 to position the connecting piece 200, and after the positioning pin 600 is pulled out, the connecting piece 200 can be removed from the mounting part 112, realizing the detachable connection of the connecting piece 200 and the sleeve 100.

[0040] When the positioning pin 600 is installed, in order to prevent the positioning pin 600 from falling off, the annular elastic member 700 (such as a sealing ring) can be sleeved on the outside of the positioning pin 600, and the annular elastic member 700 is just clamped in the groove 120; the advantage of using the annular elastic member 700 to fix the positioning pin 600 is that the installation and disassembly are convenient and fast, and the quick assembly and disassembly of the connecting piece 200 and the sleeve 100 can be realized.

[0041] The wrench head 300 is a rod member, which is axially slidably inserted into the first wrenching part 111 and passes out of the shuttle hole 210, and the wrench head 300 and the shuttle hole 210 are both configured as hexagonal structures, so that the wrench head 300 and the connecting piece 200 are limited to be unable to rotate relative to each other; one end of the wrench head 300 close to the first wrenching part 111 is configured as a second wrenching part 310 adapted to an internal hexagonal bolt, and in the axial direction of the second wrenching part 310, a limiting part 320 protruding radially is arranged behind the second wrenching part 310, and the limiting part 320 limits the second wrenching part 310 from passing out of one end of the shuttle hole 210 close to the first wrenching part 111.

[0042] The connecting piece 200 can be provided with the shuttle hole 210 of different sizes to meet the passing of the wrench head 300 of different sizes. Since the connecting piece 200 is detachably connected with the sleeve 100, by replacing the connecting piece 200 with the shuttle hole 210 of different sizes, the combination of the wrench head 300 of different sizes with the sleeve 100 can be realized, and the assembly requirement of the combination of the inner hexagonal bolt and the outer hexagonal bolt can be met.

[0043] The magnet 800 is configured as a ring-shaped piece and is arranged at the end of the connecting piece 200 close to the first wrenching part 111, and can generate a magnetic attraction force inside the first wrenching part 111.

[0044] One end of the quick pull gun head 500 can be detachably connected with the end of the wrench head 300 protruding out of the shuttle hole 210, and the other end of the quick pull gun head 500 can be connected with a tightening gun. The outer wall of the quick pull gun head 500 is further provided with an anti-skid part 510.

[0045] The quick pull gun head 500 in the embodiment can be converted by using a common tightening gun adapter on the market, and the quick connection of the wrench head 300 with the tightening gun can be realized, and the specific structure will not be described in detail.

[0046] The spring 400 is sleeved on the part of the wrench head 300 protruding out of the shuttle hole 210, and the spring 400 is compressed between the end of the quick pull gun head 500 and the end surface of the connecting piece 200. When the sleeve 100 is pulled backward along the axial direction of the wrench head 300, the spring 400 is compressed.

[0047] The embodiment provides a use method of the wrench head and sleeve connecting piece device.

[0048] In the initial state, since the spring 400 pushes the sleeve 100 to the most front end, the second wrenching part 310 of the wrench head 300 is retracted into the first wrenching part 111, and at this time, the first wrenching part 111 can be used to preferentially assemble the outer hexagonal bolt. Due to the presence of the magnet 800, the magnetic attraction force can be generated inside the first wrenching part 111, and the removed outer hexagonal bolt will not fall randomly under the adsorption of the magnetic attraction force. When the outer hexagonal bolt needs to be removed, the sleeve 100 can be pulled backward along the axial direction of the wrench head 300, at this time, the second wrenching part 310 of the wrench head 300 protrudes out of the first wrenching part 111, and the outer hexagonal bolt is ejected and falls to the storage position.

[0049] When it is necessary to assemble an Allen bolt, the sleeve 100 is pulled back along the axial direction of the wrench head 300, the second wrenching part 310 of the wrench head 300 is stretched out of the first wrenching part 111, and then the second wrenching part 310 is directly inserted into the Allen bolt for tightening or loosening operation.
