Abstract
The utility model discloses a kind of overheat proof electric wrench, including, inside set the handle of the main casing and connection of drive component on a main housing, the head capsule that the main casing front end is held when being and using, the output shaft of the drive component stretches out from head capsule, is cased with preventing hot head capsule protective cover on the head capsule.The head capsule protective cover used in the utility model can effective heat-insulation scald-proof, prevent use when electric wrench slip.And head capsule protective cover and main casing stable connection, it is not easy to release.
Description
Technical field
The utility model belongs to assembly tool field, more particularly to a kind of overheat proof electric wrench.
Background technology
Electric wrench is broadly divided into impact wrench, torsion is cut spanner, constant torque wrench, corner spanner, angular spanner, hydraulic pressure and pulled
Hand, torque spanner, rechargeable electric wrench.Impact wrench is the instrument for screwing screw, bolt, fixture etc..Impact wrench
There is extremely strong impulsive force when in use, it is necessary to which user is fixed with hand.Due to running at high speed for Wrench head internal impact part
Substantial amounts of heat is produced, the head capsule position of Wrench head is extremely scalded one's hand, and influences the lasting use of spanner.And because electric wrench uses
Shi Yinwei impulsive forces and caused vibrations, easily slip.
Utility model content
Problem to be solved in the utility model is：A kind of overheat proof electric wrench is provided.
To solve the above problems, technical scheme provided by the utility model is:A kind of overheat proof electric wrench, including, it is interior
If the handle of the main casing of drive component and connection on a main housing, the main casing front end is head capsule, the drive component
Output shaft stretches out from head capsule, in the technical program, in addition to head capsule protective cover is cased with the head capsule.
Further, in addition to the head capsule protective cover is rubber head capsule protective cover.
Further, some projections are provided with the inside of the head capsule protective cover, are provided with by the projection and head capsule surface
The installation of rubber head capsule protective cover is realized in the cooperation of recess.
Further, the head capsule protective cover bottom is provided with groove, is provided with by the groove with main casing front end convex
Being connected for rubber head capsule protective cover and main casing is realized in the cooperation of muscle.
Further, the rubber head capsule protective cover surface is provided with anti-skid bulge with anti-skidding.
Another technical scheme provided by the utility model is：A kind of overheat proof electric wrench, construction package and a upper technology
It is identical in scheme.Internal thread is provided with the inside of rubber head capsule protective cover, the external screw thread being provided with by the internal thread and head capsule surface
Cooperation realize the installation of head capsule cover.
Further, the screw thread is Tang thread, and same section of thread segment is compounded in by left-handed and two kinds of helixes of dextrorotation
On, solve locking problem using screw thread own characteristic.
The utility model has the advantages that:
1. the head capsule protective cover in summary, used in the utility model can effective heat-insulation scald-proof, prevent use when it is electronic
Spanner slips.And head capsule protective cover and main casing are completely embedded, it is not easy to release.
Brief description of the drawings
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
Fig. 1 is the structural representation that this electric wrench does not install rubber head capsule protective cover；
Fig. 2 is the structural representation that this electric wrench is provided with rubber head capsule protective cover；
Wherein:1 output shaft, 2 handles, 3 main casings, 4 head capsules, 5 rubber head capsule protective covers.
Embodiment
Embodiment 1:Electric wrench as shown in Figure 1, including the interior main casing 3 for setting drive component and connection are on a main housing
Handle 2, the front end of main casing 3 is head capsule 4, and the output shaft 1 of the drive component stretches out from head capsule 4.Head capsule 4 is externally provided with
Rubber head capsule protective cover 5.The surface of rubber head capsule protective cover 5 is provided with anti-skid bulge with anti-skidding (being not drawn into figure).Its inner side
(it is not drawn into provided with some projections in figure), rubber head capsule is realized in the cooperation for the recess being provided with by the projection and the surface of head capsule 4
The installation of protective cover 5.The bottom of rubber head capsule protective cover 5 is provided with groove, the convex tendon being provided with by groove and the top of main casing 3
Cooperation realize the connection of rubber head capsule protective cover 5 and main casing 3, can effectively prevent rubber head capsule protective cover 5 from releasing.
Embodiment 2：Compared with Example 1, the bottom of rubber head capsule protective cover 5 is not provided with groove in the present embodiment, interior
Side is not provided with projection.Internal thread is provided with the inner side of rubber head capsule protective cover 5, is provided with by the internal thread and the surface of head capsule 4
Externally threaded cooperation realize the installation of rubber head capsule protective cover.The preferred Tang thread of internal thread, by left-handed and dextrorotation two
Kind helix is compounded on same section of thread segment, can effectively prevent rubber head capsule protective cover 5 from releasing.
For examples detailed above only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with technique
People is can to understand content of the present utility model and implement according to this, can not limit the scope of protection of the utility model with this.It is all
The equivalent transformation done according to the utility model Spirit Essence or modification, should all cover the scope of protection of the utility model it
It is interior.
