Description

A kind of chest expander

Technical field

The utility model relates to a kind of chest expander, belongs to Weaving device technical field.

Background technology

In textile industry, often can run into two less parts and be bonded together by external force, how by two complete separating of parts, be a very tall order.For example, bearing be taken out from axle, just need to take very large power, sometimes also can feel not have effectively place to make.

Therefore, in order to solve above technical problem, designed a kind of chest expander, this chest expander can be by complete two little parts that are bonded together separating, saved the working time, improved operating efficiency, this chest expander is simple in structure, easy to use, own vol is little, is easy to carry.

Utility model content

In order to overcome the defect existing in background technology, the utility model solves the technical scheme that its technical problem adopts: a kind of chest expander, comprise lag screw, fixed head, clamping rings, hold-down screw one, hold-down screw two, attachment screw one, attachment screw two, upper hold-down nut and lower hold-down nut, described lag screw passes from the middle part of fixed head by screw thread, described hold-down screw one and hold-down screw two pass from the both sides of fixed head, the bottom of described hold-down screw one and hold-down screw two is fixed on clamping rings, on described hold-down screw one and hold-down screw two, be respectively equipped with a upper hold-down nut and a lower hold-down nut, described fixed head is between upper hold-down nut and a lower hold-down nut.

A kind of chest expander that the utility model is related, this chest expander can, by complete two little parts that are bonded together separating, have been saved the working time, improved operating efficiency, this chest expander is simple in structure, easy to use, own vol is little, is easy to carry.
