Detailed Description

The present invention will be further described with reference to the following examples, which are not intended to limit the scope of the present invention, but are intended to be covered by the appended claims in any way.

Referring to fig. 1-2, the present invention provides a starter convenient to install, including a starter body 1 and a flange 2. An inner cylinder 3 is arranged on one side of the flange 2, and an outer cylinder 4 is slidably sleeved on the outer side of the inner cylinder 3. Namely, the outer cylinder 4 is sleeved on the inner cylinder 3 to form a telescopic structure. Specifically, be equipped with T type slide rail on the outer wall of interior barrel 3, be equipped with T type spout on the inner wall of outer barrel 4, T type slide rail slidable mounting realizes the sliding connection of interior barrel 3 and outer barrel 4 in the T type spout, has also carried on spacingly to outer barrel 4 simultaneously. Preferably, the tip of interior barrel 3 is equipped with a plurality of installation ears, has seted up the through-hole on the installation ear, also set up on the ring flange 2 with the through-hole one-to-one's spliced eye on the installation ear, interior barrel 3 can dismantle with ring flange 2 through the locking bolt of grafting in through-hole and spliced eye and be connected to the dismouting of barrel, the nimble use of the user of being convenient for.

A screw rod 5 is arranged in the inner cylinder 3, and one end of the screw rod 5 is in threaded connection with the inner cylinder 3. One end that screw rod 5 and interior barrel 3 are connected outwards extends has locating lever 6, and locating lever 6 and screw rod 5 formula structure as an organic whole. The locating rod 6 activity is pegged graft downthehole at the flange of ring flange 2, and the locating rod 6 extends to the outside in flange hole. During installation, the positioning rod 6 can be inserted into an installation hole of an engine, so that the starter is positioned. It should be noted that the radial dimension of the positioning rod 6 is smaller than the radial dimension of the screw 5, so as to facilitate the insertion and installation of the positioning rod 6. The other end of screw rod 5 is equipped with a stopper 7, and the rear of stopper 7 extends has main shaft 8, and main shaft 8 rotates with outer barrel 4 and is connected. Specifically, the main shaft 8 is rotatably connected to the outer cylinder 4 through a first bearing 19. A gear driving mechanism is arranged on the main shaft 8, and a driving end of the gear driving mechanism penetrates through the outer cylinder body 4.

Preferably, the end face of the limiting block 7 close to the screw 5 is provided with stripes.

The gear drive mechanism comprises a first bevel gear 9 and a second bevel gear 10. The first bevel gear 9 is fixedly installed on the main shaft 8, the second bevel gear 10 is installed on the outer cylinder 4 through a rotating shaft 11 in a rotating mode, the first bevel gear 9 is connected with the second bevel gear 10 in a meshed mode, and the rotating shaft 11 penetrates through the outer cylinder 4 and extends to the outer side of the outer cylinder 4. An operation sleeve 12 is fixedly installed at one end of the rotating shaft 11 extending to the outer side of the outer cylinder 4, and a hexagonal operation cavity 13 is formed in the operation sleeve 12. During operation, the inner hexagonal wrench is inserted into the hexagonal operation cavity 13, and then the inner hexagonal wrench is rotated manually or through an electric tool, so that the screw 5 can be rotated. In addition, the side wall of the inner cylinder 3 is provided with a through groove for inserting the rotating shaft 11.
