Abstract
The utility model discloses a three-jaw pull tool, which comprises three pull jaws, a pull tool seat and a lead screw. A spring is disposed between the pull tool seat and at least one pull jaw, and self tensile force of the spring is larger than self weight of the pull jaw. The pull jaw which is easy to fall is fixed by the action of the spring so that the three-jaw pull tool can be conveniently used.
Description
Technical field
The utility model relates to the hardware & tools field, relates in particular to a kind of Three-claw pull-horse.
Background technology
Three-claw pull-horse is the instrument that often uses in a kind of flight-line maintenance.Mainly be used for the bearing that damages, shaft coupling etc. are disassembled from axle vertically.When existing Three-claw pull-horse level was used, the pawl in below often fell down under the gravity effect, needs frequent fixing this pawl when making operation, has influenced service efficiency.
The utility model content
The utility model technical problem to be solved is: the Three-claw pull-horse that can fix automatically in a kind of the use is provided.
In order to solve the problems of the technologies described above; The technical scheme of the utility model is: a kind of Three-claw pull-horse; Comprise three pulling claws, draw horse seat, screw mandrel, pulling claw is movably arranged on and draws on the horse seat, draws between horse seat and the screw mandrel to be connected through screw thread; Said drawing between horse seat and at least one pulling claw is provided with spring, and spring self pulling force is greater than the deadweight of pulling claw.
Said drawing between horse seat and three pulling claws all is provided with spring, and spring self pulling force is greater than the deadweight of pulling claw.
Said pulling claw is provided with first mounting blocks, and the said horse seat that draws is provided with corresponding second mounting blocks, and said both ends of the spring is connected with first, first mounting blocks respectively.
The utility model has the advantages that: because pulling claw is provided with first mounting blocks, draw the horse seat to be provided with corresponding second mounting blocks, be provided with spring between first, first mounting blocks; Spring self pulling force is greater than the deadweight of pulling claw; When level is used, make the pulling claw that is provided with spring be positioned at below, fix this pulling claw through the effect of spring; Avoid this pulling claw frequent whereabouts under the gravity effect, make that this Three-claw pull-horse is easy to use.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the structural representation of the another kind of embodiment of the utility model.
Among Fig. 1-2: 1. pulling claw, 2. draw horse seat, 3. screw mandrel, 4. first mounting blocks, 5. second mounting blocks, 6. spring.
The specific embodiment
Describe the particular content of the utility model in detail below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1, a kind of Three-claw pull-horse comprises three pulling claws 1, draws horse seat 2, screw mandrel 3; Pulling claw 1 is movably arranged on and draws on the horse seat 2; Draw between horse seat 2 and the screw mandrel 3 to be connected through screw thread, one of them pulling claw 1 is provided with first mounting blocks 5, draws horse seat 2 to be provided with corresponding second mounting blocks 4; The first, 5 of first mounting blocks are provided with spring 6, and spring 6 self pulling force is greater than the deadweight of pulling claw 1.
As shown in Figure 2; A kind of Three-claw pull-horse; Comprise three pulling claws 1, draw horse seat 2, all be provided with first mounting blocks 5 on 3, three pulling claws 1 of screw mandrel, draw horse seat 2 to be provided with three corresponding second mounting blocks 4; Second mounting blocks 4 and 5 of corresponding first mounting blocks are provided with spring 6, and spring 6 self pulling force is greater than the deadweight of pulling claw 1.
Because pulling claw 1 is provided with first mounting blocks 5, draw horse seat 2 to be provided with corresponding second mounting blocks 4, the first, 5 of first mounting blocks are provided with spring 6; Spring 6 self pulling force is greater than the deadweight of pulling claw 1; When level is used, make the pulling claw 1 that is provided with spring 6 be positioned at below, fix this pulling claw 1 through the effect of spring 6; Avoid this pulling claw 1 frequent whereabouts under the gravity effect, make that this Three-claw pull-horse is easy to use.
