A screwdriver and a ratchet mechanism thereof are disclosed. A ratchet mechanism includes: a main body base having blocking portions; a ratchet elastic sheet having abutment portions corresponding to the blocking portions; two blocking sheets retained on the blocking portions and abutted the abutment portions to be positioned between the blocking and abutment portions; a pinion having a gear portion between the blocking sheets to allow the gear portion and the blocking sheets to be adjusted between engagement/disengagement states; a positioning elastic sheet having an operating portion; a ratchet direction adjuster having contact members corresponding to the blocking sheets and an operated portion corresponding to the operating portion. The operating portion operates the operated portion, the contact members contact the blocking sheets and the blocking sheets being operated by the contact members to be in disengagement state with the gear portion to adjust the rotational direction of the gear portion.

A screwdriver includes a main body and a switch. The main body is coupled to a handle and includes a pair of parallel, spaced apart slots, and a pawl positioned in each slot. Each pawl is biased outwardly by a spring. The switch is pivotable relative to the main body, and the switch includes a groove extending along an arcuate portion of an inner surface. Pivoting the switch in a first direction moves the switch toward a first position in which the groove is positioned in-line with the first pawl. When the switch is in the first position, the first pawl extends outwardly from the slot and engages the internal tooth surface such that application of a torque in a first direction drives a shank in the first direction and application of a torque in the second direction causes the shank to ratchet relative to the main body.

A tool head with an anti-slip structure includes a combination segment formed on one side of the tool head, a driving segment formed on another side of the tool head, a groove segment formed the tool head and positioned between the combination segment and driving segment, and an anti-slip structure configured on the tool head and positioned between the groove segment and driving segment. With the anti-slip structure of a high friction coefficient and the groove segment, the friction can be increased so as to allow users to easily and quickly draw the tool head out of the hole of a removal tool.

An improved multitool features a wrench with a dynamic ratchet feature that contacts an inserted tool bit at two flat surfaces, allowing the tool to rotate the inserted tool bit. The ratchet feature ideally is provided by a cantilever beam which bends when rotated opposite the driving direction so that the inserted tool bit remains stationary while the tool is reset to its original position. A preferred embodiment features a cavity in which a tool bit is stored for convenience to the user.
