Abstract
A magnetic sleeve head belongs to a matching tool of a pneumatic wrench. The defect that the surface of a workpiece is scratched when a bolt is screwed by the sleeve head due to the fact that the depth of an inner cavity of the sleeve head is larger than the height of a bolt head in the conventional sleeve head is mainly solved. The utility model discloses a sleeve, its characterized in that sleeve inner chamber can be equipped with the magnetic path with the terminal surface that the bolt contacted. The utility model discloses can not the surface of fish tail work piece when the bolt of screwing to have simple structure, convenient to use's advantage, can improve assembly efficiency.
Description
Technical field
The utility model belongs to the kit of pneumatic impact spanner, specifically a kind of collet head that is used to tight a bolt.
Background technology
The inner chamber degree of depth of existing collet head is usually all greater than the height of bolt head, and purpose is in order to guarantee that bolt can not come off from sleeve, but its maximum drawback of bringing is: collet head tends to the surface tear with workpiece when screwing bolt.
Summary of the invention
The purpose of this utility model is a kind of simple in structure, easy to use, bolt difficult drop-off to be provided and can not to scratch the magnetic sleeve head of workpiece at above-mentioned deficiency.
The utility model is achieved in that and comprises sleeve, it is characterized in that said barrel bore can be provided with magnetic patch with the contacted end face of bolt.
Above-mentioned magnetic patch is a permanent magnet.
The utility model both can reduce the degree of depth of barrel bore by the mode of magnetic patch is set at barrel bore, also can guarantee that bolt can not come off from sleeve, thereby made collet head can not scratch the surface of workpiece when screwing bolt.The utlity model has advantage simple in structure, easy to use, can improve efficiency of assembling.
Description of drawings
Accompanying drawing is the utility model structure and user mode schematic diagram, 1---sleeve, 2---bolt, 3---magnetic patch, 4---pneumatic impact spanner.
The specific embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Embodiment: sleeve 1 inner chamber can be provided with the magnetic patch 3 that is made of permanent magnet with bolt 2 contacted end faces promptly becomes the utility model.
Owing to be provided with magnetic patch 3 in the inner chamber of sleeve 1, therefore, can reduce the degree of depth of sleeve 1 inner chamber, and, can guarantee that bolt 2 can not come off and collet head can not scratch the surface of workpiece from sleeve 1 when screwing bolt 2.During use, the utility model is installed on the pneumatic impact spanner 4 gets final product.
Claims (2)
1. a magnetic sleeve head comprises sleeve, it is characterized in that said barrel bore can be provided with magnetic patch with the contacted end face of bolt.
2. by the described magnetic sleeve head of claim 1, it is characterized in that said magnetic patch is a permanent magnet.
