Abstract
The invention discloses a handle dedicated to installation of a powder shaft sleeve. The handle is characterized by comprising a core handle and a sliding pipe, wherein a threaded hole is formed in the lower end of the core handle and is connected with a double-screw bolt; the double-screw bolt is connected with a connector; a connecting hole is formed in the lower end of the connector; an annular outer edge is arranged at the upper end of the connector; the sliding pipe is arranged on the outer sides of the connector and the core handle; the inner edge of the upper end of the sliding pipe is provided with an inner closing edge above the annular outer edge; a compression spring sleeving the core handle is arranged between the outer edge and the inner closing edge; a boss pressing the inner closing edge is arranged at the upper part of the core handle; and the lower end of the sliding pipe is connected with an ejection pipe. According to the invention, after being in place, the handle presses the sliding pipe downwards and utilizes the lower edge of the ejection pipe to jack up the shaft sleeve, so that the shaft sleeve is separated from a stretch yarn, release is stable and does not deviate, direct contact with a hand during the release process is avoided, the shaft sleeve is unlikely to be in contact with other things, high convenience and reliability are realized, and the ejection pipe also can be replaced along with change of the size of the shaft sleeve.

Part, such as oilite bushing, are widely used in various industrial trades, without machining, with unique chemical composition and machinery,
Physical property, is obtained with traditional method for metal working, the characteristics of wherein iron powder has low cost practical
And be widely used.
When existing metallurgical powder oilite bushing production and installation, because its hole is filled with lubricating oil, installing front surface also has
It is to be impregnated with lubricating oil, if fruit hand is directly taken and is easy to be infected with debris during operation, its performance is affected, because it is
Circle is held with existing instrument tweezers and discharges all unstable, and this still awaits technology solution.
The content of the invention
In order to solve the above problems, the invention provides a kind of powder axle sleeve install dedicated handle, it is possible to implement connection and
Nondestructive demounting.
The technical solution used in the present invention is：A kind of powder axle sleeve installs dedicated handle, it is characterised in that include core handle
And sliding tube, core handle lower end is provided with screwed hole, and screwed hole is connected with stud, and Stud connection has connector, and connector lower end is provided with
Connecting hole, connector upper end is provided with annular outer, and connector and core handle outside are provided with sliding tube, and sliding tube upper end inner edge is provided with position
Interior receipts edge above annular outer, outer and interior receipts are provided with the compression spring being enclosed within core handle between, and core handle top is provided with pressure
In the interior boss received on, sliding tube lower end is connected with ejection pipe.
Further, it is provided with internal thread in the connecting hole.
Further, the connecting hole bottom is soft magnetic materials.
Further, the sliding tube upper end is connected with by pressure ring.
Under inventive article normality under compression spring effect, sliding tube goes upward to and stops with boss top, ejects pipe lower end position
In elastic filament middle section, the pickup section pickup axle sleeve of now bottom connection, shifted or installed, pushed sliding tube profit afterwards in place
Push axle sleeve with ejection pipe lower edge, depart from axle sleeve and elastic filament, release is stable, will not offset, period without hand directly contact,
Axle sleeve is difficult to contact debris, and convenient reliability, ejection pipe can also be changed with sleeve size change.

Specific embodiment
The embodiment of the present invention as shown in Figure 1, 2, install dedicated handle and be provided with core handle 9 and sliding tube 15 by the powder axle sleeve,
As long as core handle is easy to grip or is held, shape is unrestricted, and the present embodiment is cylindric, and core handle lower end is provided with screwed hole
10, screwed hole is connected with stud 11, and Stud connection has connector 12, and connector lower end is provided with connecting hole 13, and it is soft to meet bottom hole portion
Magnetic material, can be connected with the pickup section adhesive with permanent magnet, can also realize and pick up by being provided with internal thread in connecting hole
The connection in portion is taken, connector upper end is provided with annular outer 14, and connector and core handle outside are provided with sliding tube 15, in sliding tube upper end
Edge is provided with the interior receipts above annular outer along 16, sliding tube upper end be connected with evagination by pressure ring, by outer under being easy to
The compression spring 17 being enclosed within core handle is provided between with interior receipts, core handle top is provided with and is pressed in interior receipts along upper boss 18, sliding tube
Lower end is connected with ejection pipe 19, and ejection pipe can be moved up and down outside elastic filament with sliding tube, and ejection pipe lower end can be with axle sleeve upper end
Stop along top, realize that axle sleeve is separated, can change with sleeve size change.
Change as individual components when the present invention is used, pickup section can be coordinated to use, pickup section is provided with core pipe 1 and elastic force
Silk, elastic filament is three, can be curved by wire, or plastic material, as long as just can be with elastic filament epimere with elasticity
2 is straight portions, and the epimere of three elastic filament is inserted and secured in core pipe by core pipe lower end, and three elastic force epimere silks are squeezed in core pipe
Interior enforcement is fixedly connected, and the present embodiment is more stable in order to connect, and is provided with three elastic filament upper section central positions and its swelling exists
