Drawings
FIG. 1 is a schematic view of a fastener removing apparatus according to the present invention.
Detailed Description
The present invention is described in further detail below with reference to the drawings to enable those skilled in the art to practice the invention by referring to the description.
As shown in fig. 1, the fastener removing device of the present invention includes a handle and a locking strap 4, wherein the locking strap 4 locks the fastener 3 in a sleeved manner, and the handle drives the locking strap 4 to unscrew or tighten the fastener 3.
To prevent the boot strap 4 from slipping when unscrewing or tightening the fastener 3, the handle of the present invention includes a support handle 1 and a locking handle 2, with the end 11 of the support handle 1 pivotally connected to the end 21 of the locking handle 2 via a shaft 10.
One end 41 of the lock strap 4 is fixedly connected with the front end 12 of the supporting handle 1, and the other end 42 of the lock strap 4 passes through the space between the front end 12 of the supporting handle 1 and the front end 22 of the locking handle 2 after bypassing the fastening piece 3 and is clamped and fixed by the front end 12 of the supporting handle 1 and the front end 22 of the locking handle 2.
In addition, an arc-shaped pressing block 23 corresponding to the outer edge 31 of the fastener 3 is pivotally arranged at the front end 22 of the locking handle 2, and an auxiliary pressing handle 24 is combined and arranged on the locking handle 2. When the auxiliary pressing handle 24 is pulled by an external force, the auxiliary pressing handle 24 drives the arc-shaped pressing block 23 to rotate towards the direction of the fastening piece 3, and the sleeve locking belt 4 is pressed and fastened on the surface of the outer edge 31 of the fastening piece 3. Further, a plurality of clamping ribs 231 can be further arranged on the arc-shaped compaction block 23 towards the arc-shaped surface of the fastener 3, so as to enhance the anti-slip effect on the sleeve-locking belt 4.
When the fastener dismounting device disclosed by the invention is used, the front end 12 of the supporting handle 1 and the front end 22 of the locking handle 2 have extremely strong clamping force due to the abutting action of the outer edge 31 of the fastener 3 on the front end 22, so that the sleeve locking belt 4 which bypasses the fastener 3 can be sufficiently clamped to prevent the slip; further, the arc-shaped pressing block 23 also presses and fastens the sleeve-locking belt 4 on the surface of the outer edge 31 of the fastener 3 under the pushing action of the auxiliary pressing handle 24, so that the clamping and fixing effect of the sleeve-locking belt 4 on the fastener 3 when the fastener is disassembled is ensured.
In the present invention, a gripping protrusion 221 protruding toward the front end 12 of the support handle 1 is provided at the front end 22 of the locking handle 2, and an anti-slip rib 222 is provided at a side of the gripping protrusion 221 contacting the fastening member 3. When the fastener 3 is unscrewed or screwed, the clamping protrusion 221 clamps and fixes the locking strap 4 with the front end 12 of the support handle 1, and the anti-slip rib 222 presses and fastens the locking strap 4 to the surface of the outer edge 31 of the fastener 3. Further, a clamping groove 123 corresponding to the clamping protrusion 221 may be formed on the support handle 1, and the clamping protrusion 221 abuts against the lock strap 4 and is clamped into the clamping groove 123, so as to better prevent the lock strap 4 from moving.
In the invention, in order to facilitate replacement of the damaged sleeve locking belt 4, a clamping groove 121 is formed in the supporting handle 1, and a penetrating groove 122 is formed between the clamping groove 121 and the end surface of the front end 12 of the supporting handle 1 opposite to the fastening piece 3. The sleeve lock belt 4 comprises a belt body 412 and a head 411 combined with the end part of the belt body 412, the head 411 is correspondingly clamped into the clamping groove 121, and the belt body 412 connected with the head 411 is led out after passing through the penetrating groove 122.
As shown in fig. 1, in the present invention, the auxiliary pressing handle 24 includes a hand pulling handle 241 and a transfer handle 242. The front end 2411 of the handle 241 is pivotally connected to the middle of the locking handle 2, and the end 2413 of the handle 241 is a free end. The end 2421 of the transfer handle 242 is pivotally connected to the middle portion of the handle 241, and the front end 2423 of the transfer handle 242 is pivotally connected to the front end 232 of the arc-shaped pressing block 23. When the tail end 2413 of the handle 241 is pulled away from the locking handle 2 by an external force, the handle 241 pushes the switching handle 242, and the arc-shaped pressing block 23 is pushed by the switching handle 242 to rotate towards the direction of the fastening piece 3, so that the sleeve locking belt 4 is pressed and fastened on the surface of the outer edge 31 of the fastening piece 3.
In order to ensure that the control process of the arc-shaped pressing block 23 is more visual and predictable, and also to match the arc-shaped shape of the contact surface of the arc-shaped pressing block 23 and the fastening piece 3 to realize more balanced stress, the switching handle 242 is further provided with a curved arc shape, and the distance from the pivot point 2422 of the switching handle 242 on the handle 241 to the pivot point 2412 of the handle 241 on the locking handle 2 is equal to the distance from the pivot point 2424 of the switching handle 242 on the arc-shaped pressing block 23 to the pivot point 233 of the arc-shaped pressing block 23 and the front end 22 of the locking handle 2.
Although embodiments of the present invention have been disclosed above, it is not limited to the details and embodiments shown and described, it is well suited to various fields of use for which the invention would be readily apparent to those skilled in the art, and accordingly, the invention is not limited to the specific details and illustrations shown and described herein, without departing from the general concepts defined in the claims and their equivalents.
