Detailed Description

The present invention will be described in detail below, and it is apparent that the technical solutions in the embodiments of the present invention are described clearly and completely. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model discloses an improve and provide novel adjustable torque wrench here, the technical scheme of the utility model is:

as shown in fig. 1-4, the novel adjustable torque wrench comprises an upper cover 1, an operating handle 10, a screwdriver 7, a clamp spring groove 11 is formed in the middle position of the outer side of the screwdriver 7, a clamp spring 8 is clamped in the inner side of the clamp spring groove 11, a lower gear 6 is fixedly sleeved in the upper position of the clamp spring groove 11 in the outer side of the screwdriver 7, an upper gear 5 is sleeved in the upper position of the lower gear 6 in the outer side of the screwdriver 7, a spring 4 is arranged on the upper end of the upper gear 5, an upper gasket 3 is arranged on the upper end of the spring 4, a tooth cover 2 is arranged on the upper end of the upper gasket 3, the tooth cover 2 is rotatably connected with the inner side of the operating handle 10 through threads, the screwdriver 7 penetrates through the inside of the operating handle 10, the tooth cover 2, the upper gasket 3 and the spring 4 are sleeved in the outer side of the screwdriver 7, and a lower gasket 9 is arranged on the lower end position of the lower gear 6 in the outer side of the screwdriver 7.

Furthermore, the upper cover 1 and the operating handle 10 are clamped and fixed, and the upper cover 1 and the operating handle 10 are convenient to detach, so that the tooth cover 2 on the inner side of the operating handle 10 can be rotated, and the torque force of the wrench can be adjusted.

Furthermore, the upper gasket 3, the spring 4, the upper gear 5, the lower gear 6, the screw driver 7, the clamp spring 8 and the lower gasket 9 are all made of metal components, and the metal components have higher strength and improve the durability of the wrench.

Furthermore, the upper cover 1 and the operating handle 10 are both made of plastic, and the plastic components are light in weight, so that the spanner is convenient to operate and use.

Furthermore, teeth between the upper gear 5 and the lower gear 6 are meshed with each other, and teeth between the upper gear 5 and the lower gear 6 are meshed with each other, so that the rotating torque of the upper gear 5 can be transmitted to the lower gear 6, and the screwdriver 7 is driven to rotate.

Further, the outside of going up gear 5 is the hexagon structure, and goes up gear 5 and fix through the inboard of hexagon structure with operating handle 10, when rotating operating handle 10, can drive gear 5 through the hexagon structure and rotate, and then drive bottle opener 7 and rotate.

Furthermore, the upper end of the tooth cover 2 is provided with an adjusting hole, and the adjusting hole is convenient for driving the tooth cover 2 to rotate through a tool, so that the compression amount of the spring 4 is adjusted.

The working principle is as follows: when the screwdriver is used, the upper cover 1 and the operating handle 10 are rotated, the operating handle 10 drives the upper gear 5 on the inner side to rotate clockwise, the spring 4 releases elasticity to press the upper gear 5 on the upper side of the lower gear 6, teeth between the upper gear 5 and the lower gear 6 are mutually occluded, therefore, the upper gear 5 can drive the lower gear 6 to rotate when rotating, the lower gear 6 can drive the screwdriver 7 to rotate clockwise, the screwdriver 7 can drive the screw to rotate, when the rotating torque force is larger than a certain value, the resistance on the screwdriver 7 and the lower gear 6 is increased, and at the moment, the upper gear 5 continues to rotate clockwise, at the moment, the teeth between the upper gear 5 and the lower gear 6 are separated, and the upper gear 5 and the lower gear 6 move upwards to compress the spring 4, namely, the rotation is generated between the upper gear 5 and the lower gear 6, the transmission of the torque has been interrupted, consequently, play fine guard action, prevent that the torque from too big damaging the screw thread, when needing to adjust the torque size, dismantle the separation with upper cover 1 and operating handle 10, then use tools rotates tooth lid 2, tooth lid 2 rotate through with operating handle 10 between the screw-thread engagement downstream, compress spring 4, compress more length with spring 4, make spring 4 can release bigger pressure, thereby make between upper gear 5 and the lower gear 6 more inseparable of tooth interlock, thereby the upper limit that the torque was set for has been improved, can provide bigger torque output, can be according to different screw intensity, adjust the output torque size of spanner in a flexible way, the practicality has been improved.
