Head；The lever and cam mechanism includes cam and lever sleeve；The separating mechanism includes mandril and slide；Two pieces of support plates
Spacing is fixed on base；The cam is hinged by axis pin and two pieces of support plates；Lever sleeve is fixed on the non-of cam afterbody
In working profile；The working profile of cam and the afterbody of mandril form cam pair；The mandril forms sliding pair with slide；Bullet
Spring is nested with mandril, and one end is fixed with mandril, and the other end is fixed with slide；The slide is fixed on base；Determine dividing plate
Both ends are fixed respectively with two pieces of support plates；Dynamic dividing plate both ends respectively open up a cylindrical hole, are opened in two of determine dividing plate both ends
Threaded hole is bolted with dynamic dividing plate corresponding end through hole respectively；The threaded hole opened up in the middle part of dynamic dividing plate is connected with screw thread pressure
Head；The chain stays are arranged between dynamic dividing plate and dynamic dividing plate；The groove opened up along its length at the top of chain stays is divided into two
Part, relatively thin part are intermediate bulkhead, and thicker part is chain positioning plate；It is equipped with intermediate bulkhead and chain positioning plate
The multiple teeth equidistantly arranged, and the position of tooth corresponds on intermediate bulkhead and chain positioning plate.
Be equipped with transition arc at tooth root with teeth.
The screw thread pressure head uses hexagon socket head cap screw.
The utility model has the following advantages：The ingenious dual power-saving function that make use of cam lever, cam-and-
Separating mechanism linkage is driven to realize the fractionation of chain, its is easy to operate, efficient, speed is fast, and very safe, according to different rule
Lattice chain stays are suitable for a variety of various sizes of chains and split.
Brief description of the drawings
Fig. 1 is the overall structure stereogram of the utility model；
Fig. 2 is the schematic top plan view of the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As illustrated in fig. 1 and 2, a kind of lever and cam chain splitter, including workbench, base 1, lever and cam mechanism, point
Disembark structure, determine dividing plate 9, dynamic dividing plate 5, chain stays 6 and screw thread pressure head 10；Lever and cam mechanism includes cam 3 and lever sleeve 4；
Separating mechanism includes mandril 2 and slide 7；Base 1 is fixed on the table, and two pieces of 8 spacing of support plate are fixed on base 1；Cam 3
It is hinged by axis pin and two pieces of support plates 8；Lever sleeve 4 is fixed in the inoperative profile surface of 3 afterbody of cam；The work of cam 3 is wide
Face and the afterbody of mandril 2 form cam pair；Mandril 2 forms sliding pair with slide 7；Spring is nested with mandril 2, one end and mandril
2 fix, and the other end is fixed with slide 7；Slide 7 is fixed on base 1；9 both ends of determine dividing plate are fixed respectively with two pieces of support plates 8；It is dynamic
Partition plate both ends respectively open up a cylindrical hole, be opened in two threaded holes at determine dividing plate both ends respectively with 5 corresponding end of dynamic dividing plate
Through hole is bolted；The threaded hole opened up in the middle part of dynamic dividing plate is connected with screw thread pressure head 10；Chain stays 6 be arranged on dynamic dividing plate with
Between dynamic dividing plate；The groove that the top of chain stays 6 is opened up along its length is divided into two parts, and relatively thin part is intermediate bulkhead, compared with
Thick part is chain positioning plate；Four teeth equidistantly arranged, and intermediate bulkhead are equipped with intermediate bulkhead and chain positioning plate
Corresponded with the position of tooth on chain positioning plate, transition arc is equipped with tooth root with teeth.
Chain stays 6 have multiple tooth pitches specification and facewidth specification.
Screw thread pressure head uses hexagon socket head cap screw, convenient to be screwed using allen wrench.
Workbench uses wood materials or iron.
The operation principle of the lever and cam chain splitter：
Chain is placed in chain stays, the alignment of pin on chain link be placed on chain stays two tooth of chain positioning plate it
Between, both sides chain clamping plate, which is individually positioned in chain positioning plate both sides, (has side chain clamping plate insertion intermediate bulkhead to determine with chain
Between the plate of position)；After the pin alignment mandril 2 of chain link to be treated, the bolt in two threaded holes of determine dividing plate is screwed, then
Screw thread pressure head 10, chain is secured firmly in chain stays.Then lever sleeve is pressed downward with hand, cam 3 is made with mandril 2
Slided with mandril 2 is promoted, you can extrude the pin on chain link, chain separation.After loosing one's grip, mandril 2 is replied under the action of the spring
To initial position.
Wherein, the bolt in two threaded holes of determine dividing plate is used for the clamping for adapting to different size chain stays 6, and intermediate bulkhead rises
Position-limiting action, can prevent screw thread pressure head from screwing off excessively, damage chain.
