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 and 2, the fastener unscrewing and tightening tool of the invention comprises a handle and a sleeve locking belt 4, wherein the sleeve locking belt 4 is used for sleeve locking a fastener 3, and the handle drives the sleeve locking belt 4 to unscrew or tighten the fastener 3.
In the invention, the handle specifically comprises a supporting handle 1 and a locking handle 2, and the tail end 11 of the supporting handle 1 and the tail end 21 of the locking handle 2 are pivoted together through a shaft 10, so that the supporting handle 1 and the locking handle 2 can rotate relatively relative to the 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.
The invention uses the acting force of the handle when the fastener 3 is disassembled to ensure that extremely strong clamping force is generated between the front end 12 of the supporting handle 1 and the front end 22 of the locking handle 2, so that the winding length of the sleeve locking belt 4 is not changed after the fastener 3 is wound. At this time, the sleeve locking belt 4 is pressed and attached to the surface of the fastener 3 by the acting force applied to the locking handle 2 when the handle is pulled, so that the sleeve locking belt 4 can be completely prevented from moving relative to the fastener 3, and the smooth operation of the fastener disassembly is facilitated.
Specifically, a gripping protrusion 221 protruding toward the front end 12 of the support handle 1 may be provided at the front end 22 of the locking handle 2, and an anti-slip rib 222 may be 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 fastener 3.
In order to better prevent the sleeve locking belt 4 from moving relative to the fastener to influence the smooth disassembly, an auxiliary pressing block 5 is rotatably arranged at the front end 22 of the locking handle 2, which faces away from the clamping convex part 221. The locking handle is characterized by further comprising a propping sliding block 6 arranged on the locking handle 2, wherein the propping sliding block 6 is used for propping the auxiliary pressing block 5 towards the direction of the fastening piece 3 and pressing and fastening the sleeve locking belt 4 on the surface of the fastening piece 3.
Specifically, the abutment slider 6 includes an elongated block, the front end of which is folded to form a tip 61, and a locking rib (not shown) is provided on the back of the block. A clamping chute (not shown in the figure) is arranged on one side of the locking handle 2, which is opposite to the supporting handle 1, and a clamping edge of the propping sliding block 6 is clamped into the clamping chute and can slide in the clamping chute. That is, the abutment slide 6 can slide in a direction approaching the auxiliary pressing block 5 or in a direction departing from the auxiliary pressing block 5. When the abutment slide 6 slides toward the auxiliary pressing block 5, the tip 61 of the front end of the abutment slide 6 is inserted into the gap between the auxiliary pressing block 5 and the locking handle 2 because the auxiliary pressing block 5 is rotatably pivoted to the front end 22 of the locking handle 2. At this time, since the position of the supporting handle 1 is fixed, the position of the opposite locking handle 2 is also fixed relatively, and then the tip 61 forces the auxiliary pressing block 5 to rotate, that is, the auxiliary pressing block 5 is pressed against the fastening piece 3, and as the tip 61 is deeper into the gap between the auxiliary pressing block 5 and the locking handle 2, the auxiliary pressing block 5 is pressed against the fastening piece 3 more tightly, so that the locking belt 4 is pressed and fastened on the surface of the fastening piece 3.
The invention further comprises a locking piece 7 arranged at the rear end of the propping slide block 6, wherein the locking piece 7 can move along the locking handle 2 and lock and prop against the propping slide block 6, so that the tip 61 of the propping slide block 6 is prevented from loosening after being inserted into a gap between the auxiliary compression block 5 and the locking handle 2.
Specifically, as shown in fig. 1 and 2, the locking member 7 includes a locking hook 71, and a front end of the locking hook 71 has a contact surface 711 perpendicular to the locking handle 2. The rear end of the propping sliding block 6 is a vertical surface 62 vertical to the locking handle 2, and a contact surface 711 of the locking hook 71 is attached to the vertical surface 62 of the propping sliding block 6. A plurality of locking clamping holes 81 are formed in the locking handle 2, and the locking hooks 71 are adjustably clamped in the locking clamping holes 81, so that contact surfaces 711 of the locking hooks 71 are attached to the vertical surface 62 of the abutting sliding block 6.
In actual manufacturing, the locking handle 2 may be provided with a long groove 8, and one side of the long groove 8 is provided with a plurality of locking holes 81 that are continuously arranged. The locking hook 71 comprises a bent hook body, and the front end of the hook body is a contact surface 711 perpendicular to the locking handle 2; the rear end of the hook body is provided with a clamping shaft 73, and the clamping shaft 73 is correspondingly clamped in the locking clamping hole 81. It should be noted that, the locking hole 81 may be a semicircular hole with a diameter corresponding to the locking shaft 73, and may prevent the locking shaft 73 from falling off after being locked by increasing the length of the vertical wall at the opening. Meanwhile, the distance between the edge of the vertical wall at the opening and the opposite side of the long groove 8 should be larger than the diameter of the clamping shaft 73, so that the clamping shaft 73 can be adjusted into different locking clamping holes 81 along the long groove 8.
In practical use, it should be ensured that the locking hook 71 will not rotate, so as to maintain a continuous abutment force against the vertical face 62 of the slider 6, for which purpose, a plurality of fixing insertion holes 82 parallel to the locking holes 81 are provided, and pins 83 are inserted into the fixing insertion holes 82. In use, the pin 83 is made to abut against the tail end 72 of the hook body, so that the contact surface 711 of the hook body is made to abut against the vertical surface 62 of the abutment slider 6.
In the present invention, for convenience of processing and manufacturing, the locking handle 2 and the support handle 1 are preferably made of a material having sufficient mechanical strength and appropriate toughness, such as plastic, and the locking handle 2 is formed with a gripping protrusion 221 protruding toward the front end 12 of the support handle 1, gradually increasing from the distal end 21 to the front end 22 thereof. In use, the locking handle 2 has proper toughness, so that the tail end 21 of the locking handle can be slightly bent and deformed (namely, deformed in the direction of the front end 22) after being subjected to external force, the locking hook 71 can be forced to move towards the propping slide block 6, so that the tip 61 of the propping slide block 6 is further pushed to penetrate into a gap between the auxiliary pressing block 5 and the locking handle 2, the auxiliary pressing block 5 can be more tightly propped against the fastening piece 3, and the sleeve-locking belt 4 is pressed and fastened on the surface of the fastening piece 3. Or the side of the locking handle 2 facing away from the elevation 71 is thinned, so that the bending deformation effect of the end 21 is enhanced.
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.
